摘 要:机械外骨骼是一种由钢铁的框架构成,并且可让人穿戴的机器装置,该装备可以提供额外能量来供四肢运动,可以提高单兵的速度、耐力、力量。然而当前液压、电气、电动等助力方式存在着重量大、与人体运动不完全吻合等问题,增加了人体体能消耗。针对这些难点,本文首先对机械外骨骼的执行机构进行了材料上的优化,提出了将尼龙多向人造肌肉这一新型材料代替之前液压、电气、电动等助力方式,并进行了可行性分析,在FPGA 开发板上对控制过程进行了编程实现。

Abstract:Mechanical exoskeleton is a wearable mechanical device consisting of a steel frame,which can be supplied in an amount external energy to provide limb movement can improve the speed,endurance and strength of individual soldiers. However,the current hydraulic pressure,electrical,electric and other power-assisted modes have some problems,such as heavy weight,incomplete coincidence with human motion,and increase the consumption of human physical energy. Aiming at these difficulties,this paper firstly optimizes the material of the mechanical exoskeleton executing mechanism,and puts forward a new material of nylon multi-directional artificial muscle to replace the previous hydraulic pressure,electrical,electric and other power-assisting methods,and carries out feasibility analysis. The control process is programmed on the development board of the FPGA.
Keywords:nylon;artificial muscle;mechanical exoskeleton
